Gitox-ncgs To aZZ whom iimay concern:

Be it known that I, Gnolcon S's-Pens. a citizen of the United States, residing at Greensboro. in the county of Guilford and State of North Carolina, have invented certain new and useful Improvements in Lock ing-Brakes; and I do hereby declare the following to o. fiill, clear, and descrip tion of the invention, such as will enable others skilledin the art to which it appertains to make and. use the same.

This invention reiotes to improvements locks for vehicle Wheels, and has for an object the arrangementof improved means for clutching and holding Wheels against rotetion.

A further object of the invention is the arrangement of improved means which may be readily thrown into operation for posi tively locking the Wheels of e. veliicleeitei' the vehicle has stopped for preventing the movement of the vehicle until the v'viieels have been 11niocked,-seii means inclucling an intergearing device associated with the Wheels anti operating mechanism arranged at any convenient place on the vehicie for throwing in and out the intergeoi'ing device as may he ciesirei A still further object of the invention is the arsongementof a geer'wlioelsti'nctnre on'sozne of the wheels of 9. vehiel-fe clesignel to comet with a reciprocating locking-member which may be nioved into encl out of engagement With the teeth of the gees Wheel, whereby the gear wheel, and also" the treetion wheel connected therewith, will he either locked or unlocked.

-With these ancl othei objects in View the invention comprises novel consisnclions, combinations. and arrangement of pai'tseowiil be Hereinafter more fully de scribed and claimed.

Fig. 2 is a top plan view of the operating ports of the invention shown up plied to a vehicle. certain parts bein bsoice-n away for better illustrating the construction and arrangement.

Rigidly connected with the locking member 10 is a slide 11 which moves or reciprocates in a guide 12. The locking member 10 is secured to slide 11 in any desired way, preferably, however, by and a shaft 14. Shaft 14: extends from one side of the vehicle to the other, so that a locking member may be arranged on each side of the vehicle for en gaging the gear wheel structure on each wheel. As shown in Fig. 2 a gear wheel structure 4 is provided for wheel 3' and a locking member 10 is arranged to engage the gear wheel structure 4. The locking member 10 is rigidly connected with shaft 14, and is connected with a. slide similar to slide 11 so that both of the locking members may be reciprocated toward and from their respective gear wheel structures 4. and 4:.

In order to cause a movement of the locking members 10 and 10 toward and from their respective gear wheel structures an operating arm 15 is provided arranged with a bifurcated end 16 which spans the central part of shaft 14. The operating'arm 15 is rigidly connected with a rock shaft 17 so that when rock shaft 17 is rocked or moved movement. will be conveyed to shaft it for raising and lowering the same, and consequently for engaging and disengaging the locking members. lhe rock shaft l? is journaled in brackets 18 which are rigidly connected with the axle of the vehicle. or to any other convenient member as desired for properly supporting the shaft. Rigidly connected with the outer end of rock shaft 17 is an arm 19 to which is pivotally connected a link 20. Link 20 is arranged to extend fonvardly to any convenient point, near the front of the vehicle. and to be pivotally connected at 21 to a hand operated lever 22. l land operated lever 22 is pivotally mounted at 23 to a convenient point on the vehicle, designed to engage a'suitable rack 25. By this structure the lever 22 may be moved forwardly and locked in that position which will cause the raising of the locking members l0 and 10 and the holding of said members in a raised position. In order to positively prevent the engagement of the locking members with their respective gear structures a spring 26 is provided which engages the. vehicle structure at one end and engages the arm 19 at the opposite emf, and

continually tends to raise or maintain raised the respective locking members, and to hold the catch 2a near the forward end of rack 25. It will be evident that by a proper manipulation of lever 22 the locking members may be raised or lowered for throwing into operation the locking members 10 and 10, or if desired for withdrawing said loclr ing members. By this rangement it will be observed that the wheels are positively locked against either a for ward or rearward movement. It will also be noted that by the shape of the teeth 6 and 9 the loclting members and the gear structures will readily engage or become interlocked.

Referring more particularly to Fig 3 wherein the modified parts will be designated by additional numbers, itwill be seen that shaft 17 extends entirely across the vehicle, and is journalcd in any suitable means at the sides of the vehicle. It will also be observed that shaft 17 carries a pair of operating arms 15 instead of a single operating arm. and that these operating arms are arranged near each side of the vehicle for engaging the shaft l-t near the ends thereof.

lVhat- I claim is:

Tn a device of the combination with a vehicle of a-gear wheel connected with the hub of one of the wheels thereof said gear wheel being formed with teeth having rounded ends. a reciprocating blot-l: formed with teeth having rounded ends designed to intermesh'with the teeth of said gear wheel, when moved toone position. a reciprocating guide rigidly connected with said block, guide ways for regulating the movement of said guide, whereby said block is caused to move toward and from said gear wheel. a shaft integral with said block and parallel with the axle of the vehicle. an operating arm provi led with bifurcated ends engaging said shaft. a rock shaft supported by brackets engaging said operating arm for operating said guide and -throwing said block into and out of operation.

In testimony whereof I ailix my signature in presence of two witnesses.
